Programm StuTS 70

Everyday life is full of ambiguous speech sounds, and contextual information is known to facilitate speech perception and disambiguation. However, the integration of letters and speech sounds seems to be impaired in individuals with developmental dyslexia. In the research for my master's thesis, dyslexic adults were presented with ambiguous speech sounds combined with disambiguating text or video recordings of lip movements in a phonetic recalibration paradigm. We compared the strength of the recalibration effect between the two conditions, hypothesizing that lip movements would serve as a better disambiguating stimulus than text for this specific sample. Besides the behavioural effect, we looked at neural activation during the two conditions, using functional magnetic resonance imaging (fMRI) in order to see whether exosure to lip movements and to text elicits activation in different or similar brain areas.

In this talk, I will give a short introduction to developmental dyslexia and the audiovisual integration of speech, followed by a description of the research paradigm used in the study. Then, I will present obtained results and discuss them - ideally in dialogue with the audience.
